Remote Settings - Copy development keys to release?

I'm just starting using Remote Settings, is there a way of automatically copy all development keys to the release keys? Perhaps I missed the feature somewhere?

What would be great:
- If we create a key in the Development page, if the key doesn't already exists in Release page, then copy it with its value.
- If we create a key in the Release page, if the key doesn't already exists in Development page, then copy it with its value.
